At thirty-nine, Manon Bradshaw is a devoted and respected member of the Cambridgeshire police force, and though she loves her job, what she longs for is a personal life. Single and distant from her family, she wants a husband and children of her own. One night, after yet another disastrous Internet date, she turns on her police radio to help herself fall asleep—and receives an alert that sends her to a puzzling crime scene.

Edith Hind—a beautiful graduate student at Cambridge University and daughter of the surgeon to the Royal Family—has been missing for nearly twenty-four hours. Her home offers few clues: a smattering of blood in the kitchen, her keys and phone left behind, the front door ajar but showing no signs of forced entry. Manon instantly knows that this case will be big—and that every second is crucial to finding Edith alive.

The investigation starts with Edith’s loved ones: her attentive boyfriend, her reserved best friend, her patrician parents. As the search widens and press coverage reaches a frenzied pitch, secrets begin to emerge about Edith’s tangled love life and her erratic behavior leading up to her disappearance. With no clear leads, Manon summons every last bit of her skill and intuition to close the case, and what she discovers will have shocking consequences not just for Edith’s family but for Manon herself.
